A
lobster cyborg is a cybernetic organism which is made not by using internal implants, but by using an external shell. Unlike human cyborgs that appear human externally while being synthetic internally, a Lobster looks inhuman externally but contains a human internally.
Here is an image of one, his name is Omar. He works for an intelligence agency and is designed to survive global meltdowns. He also plays
rock music in a band on weekends; so he is known as a
rock lobster.
